Root cause of the failing Windows runs (seen in the runner logs): the Actions
shell does not inherit Flutter on PATH, so `flutter --version` failed in ~30s.
Checkout via the gitea.com mirror works fine.
Add a "Locate Flutter" step that checks PATH, the FLUTTER_ROOT repo variable,
and common Windows install locations, then prepends it via GITHUB_PATH so later
steps find flutter. Fails with a clear message if not found.

Make the Gitea CI maximally likely to produce a usable Windows .exe on a
self-hosted runner behind the GFW, since compilation must go through CI:
- Build is the priority: format/analyze/test now run with continue-on-error so
a toolchain-version lint difference can never block the actual compile.
- ONNX Runtime download: default HTTP(S)_PROXY to the local proxy
(http://127.0.0.1:7890, overridable via repo secrets) so CMake's
file(DOWNLOAD) can fetch it; documented system-install alternative.
- Checkout stays on the gitea.com mirror, with a commented manual-checkout
fallback (clones from the local Gitea) if gitea.com is unreachable.
- Artifact upload is best-effort; an explicit step prints the Release output
path so the binary is findable even if upload fails.
- Dropped the optional server job to keep the Windows build focused.
- README: documented the runner prerequisites (Flutter on PATH, VS C++ build
tools, proxy, gitea.com, host-mode runner) that the workflow can't set.

Make on-device OCR a pluggable local service so it runs locally on every
platform (not just Windows), aimed at GoodNotes/Notability-class handwriting on
low-power hardware (e.g. Zen2 APU, CPU/iGPU).
- New OcrBackend abstraction (lib/services/ocr/): selector prefers an embedded
ONNX recognition backend, falling back to the OS-native backend (Windows
WinRT), and to a clean no-op when neither is available.
- OnnxRecognitionBackend: flutter_onnxruntime session from a bundled asset,
dart:ui preprocessing (resize to 48px, CHW float32, normalized), pure-Dart CTC
greedy decode. Fully guarded — absent model/dict is a no-op; never throws.
- ocr_engine.dart kept as a thin facade (recognizeImage) delegating to the
selector, so ocr_service.dart is unchanged.
- CtcDecoder unit-tested (6 tests). flutter analyze clean; all tests pass.
- Model is not committed; tool/fetch_ocr_model.sh + assets/models/ocr/README.md
document fetching PP-OCRv4 rec + dict on the dev machine.
- CI: forward HTTPS_PROXY to the Windows build so CMake can fetch the ONNX
Runtime native lib behind the GFW; README documents the system-install
alternative. PP-OCR geometry/blank assumptions documented for on-device tuning.

The self-hosted Windows runner can't reach github.com (GFW), so the previous
workflow failed cloning actions/checkout and would also fail downloading the
Flutter SDK and the sqlite3 native binary.
- Vendor the official, SHA-256-verified sqlite3 binaries under vendor/sqlite3/
and select them via pubspec hooks.user_defines (source: test-sqlite3). Builds
and tests now run fully offline — no GitHub download, no proxy, no
LD_LIBRARY_PATH hack (removed .local-sqlite/).
- Consolidate CI into one Windows workflow: fetch actions from the gitea.com
mirror, use the runner's pre-installed Flutter (no SDK download), and use the
flutter-io.cn pub/Flutter mirrors. Server tests use the Tsinghua PyPI mirror.
- Document the offline build + China mirrors in README.

Bug fixes (Flutter):
- Wrap multi-statement DB writes (insert/update/delete note, deleteDocument,
deletePageData, OCR FTS merge, migrations) in transactions to prevent data
loss on interruption and a read-modify-write FTS race.
- Fix PdfDocument leaks on exception (try/finally dispose) and preserve image
aspect ratio when stamping images onto PDF pages.
- Guard file-picker against empty selection (was .single -> crash).
- Fix eraser ConcurrentModificationError and unmodifiable-list crash on PDF
pages; capture page synchronously on save to stop wrong-page data loss.
- Fix Riverpod DB-not-ready races, broken pull-to-refresh, settings load race,
and search N+1; transform stored annotations on PDF page rotation.
- Normalize pen pressure for devices without a pressure range.
- PPT: single source of truth for slide strokes so ink displays and exports.
UI/UX:
- Material 3 typography, theme-aware colors (dark-mode fixes), hover cursors
and right-click/visible actions on desktop, keyboard shortcuts (undo/redo/
save/find), toolbar overflow handling, friendlier empty states, semantic OCR
status badges, relative timestamps, 1-based page indicators, large-deck PPT
navigation, and a scratchpad-scope label in split view.
Server (optional backend):
- Persist JWT secret (was per-process random), block path traversal in storage,
fix CORS '*'+credentials, add OCR job ownership checks, last-writer-wins sync
guard, constant-time login, and split out heavy OCR deps so the API/tests run
without them.
CI: Gitea workflows for format+analyze+test (Linux, system sqlite) and a
Windows release build; pristine `flutter analyze`, all Flutter and server tests
green.
